Reka tuvugishe ukuri, iyo abantu benshi bumvise 'imvura ikomera ibyuma bitagira umwanda', batekereza intwari ya datasheet - 17-4PH, ahari 15-5PH, hamwe numubare utanga umusaruro ushimishije. Ukuri kumaduka, cyane cyane mubintu bigoye kandi bikozwe mumashini, ninyamaswa zitandukanye. Ntabwo ari ugukubita numero ikomeye; ni bijyanye no gucunga imbyino hagati yo kuvura igisubizo, ukwezi gusaza, hamwe no kugoreka byanze bikunze bizana nayo, byose mugihe igice akenshi ari ibintu bigoye, bikikijwe n'inkuta zishoramari. Aho niho ubumenyi nyabwo, hamwe n'imitego isanzwe, bibera.
Allure hamwe nukuri kwicyiciro cya PH
Twabonye ibibazo byinshi kuri 17-4PH. Ni ukujya. Abakiriya babona MPa 1300 kandi bakibwira ko ari ugusimburwa-gusimbuza imbaraga zose zikenewe. Ariko nabonye imishinga isitara hanze yumuryango kuko batitaye kumiterere. Dutangiriye kububiko, guhimba, cyangwa gukina? Kuri sosiyete nkiyacu, Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), aho gushora imari ni inzira yibanze, inkuru itangirana na chimie ya melt na as-cast condition. Uburinganire bwibisubizo byahujwe mbere yuko dutekereza no gusaza ni ngombwa. Gukina birashobora kugira micro-gutandukanya akabari gakozwe ntigukora, bishobora kuganisha kubisubizo bidahuye nyuma.
Noneho hariho gahunda yo gutunganya. Waba ukora imashini muburyo bwakemuwe (byoroshye, byoroshye kubikoresho) hanyuma imyaka? Cyangwa urashaje mbere hanyuma ukagerageza gukora imashini 40+ HRC? Ubwa mbere mubusanzwe burusha ubwenge, ariko ugomba guteka mugihe cyo kuva mubusaza mukwihanganira. Ibi twabyize inzira igoye hakiri kare hamwe numubiri wa valve. Yayikoresheje neza muburyo bwa A, irashaje, ugasanga ibipimo binini bya bore byariyongereye birenze urugero. Byabaye ngombwa ko wongera gukemura kuvura ibintu byose no kongera gukora imashini, nisomo rihenze mumagare yubushyuhe.
Iragutera gutekereza neza. Guhitamo ntabwo ari ibyuma bidafite umwanda gusa, ni urunigi rwibikorwa: guta ubunyangamugayo -> igisubizo anneal uburinganire -> amafaranga yo kubanziriza imashini - - kugenzura gusaza -> kurangiza byanyuma. Kubura umurongo uca urunigi. Niyo mpanvu kubice byukuri-byizewe, dukunze gukorana nitsinda ryabakiriya ba injeniyeri kuva kuri CAD, atari mugihe RFQ iguye.
Imiterere H900 na H1150: Ntabwo ari Ubushyuhe gusa
Ibisaza bisanzwe (H900, H1025, H1150) ni intangiriro, ntabwo ari ubutumwa bwiza. H900 iguha imbaraga zo hejuru ariko gukomera. Kubikoresho byo kumanuka twakoraga, spec yahamagaye H900. Ariko mugihe cya prototyping, ibizamini bya Charpy kubushyuhe buke byari imipaka. Twagize ikiganiro kirekire na metallurgiste wumukiriya. Turashobora kwigurira imbaraga nkeya kugirango tuvunike neza? Twakoresheje icyiciro kuri H925 hanyuma H950, tugerageza tensile n'ingaruka. H950 yaduhaye impirimbanyi ikwiye - imbaraga zari zikiri hejuru yubushakashatsi ntarengwa, ariko ingaruka zasimbutse. Byemejwe nkubundi buryo bwo gusaza. Datasheet ntabwo yatubwiye ko; kugenzurwa no kugerageza no gukora injeniyeri yakoze.
Aha niho imyaka 30-yongeyeho muri casting na Imashini ya CNC yishura. Utezimbere kumva uburyo ibintu bigenda. Gukomera kw'imvura ibinyobwa, mugihe cyo gusaza, ntugakomere gusa; bahura nimpinduka zifatika. Kubintu bigoye, bidafite ishoramari ryamazu, ibi ntabwo ari bimwe. Twatangiye gukoresha ibizamini byo gutamba ibitambo biva kumasuka amwe, bifatanye nibice byingenzi byigice binyuze mumarembo yoroheje. Turasaza inteko yose, hanyuma tugabanye ama coupons kugirango dukomere kandi tugenzure ibipimo. Nintambwe yinyongera, ariko ishushanya igisubizo cyo gusaza mugice cya geometrie, ikiza intimba nyuma.
Reka tuganire kubyerekeye kongera gukora. Byagenda bite mugihe igice cyashaje hanyuma kigakenera gusanwa? Ninzozi mbi. Ubushyuhe bwo gusudira hejuru yimyaka HAZ, kurema akarere koroheje. Akenshi ugomba gusubira mubisubizo byuzuye anneal, ishobora gutobora igice, hanyuma ukongera gukora imashini hanyuma ukongera. Rimwe na rimwe, birarenze kubisiba. Ngiyo ngingo yingenzi dushimangira mugihe cyo gusuzuma QSY: niba gusudira aribishoboka ejo hazaza, birashoboka urwego rutandukanye rwa ibyuma ni byiza, nubwo imbaraga zambere ziri hasi. Igiteranyo cyubuzima bwose cyatwaye ibintu.
Umuti udasanzwe wuzuye: PH na Maraging
Iki ni ikintu gishimishije. Turakorana kandi idasanzwe nka maraging ibyuma. Abakiriya rimwe na rimwe babitiranya na PH idafite umwanda. Byombi bishimangira imvura, ariko ibyuma bya maraging ni fer-nikel hamwe na cobalt, molybdenum, titanium - nta chromium yo kurwanya ruswa. Ni inyamaswa zitandukanye. Umuti wabo wo kuvura nuburyo bworoshye bwo gukonjesha no gukonjesha ikirere, bikora martensite yoroshye. Gusaza noneho bigusha intermetallics. Kugoreka akenshi biri munsi ugereranije na PH idafite umwanda, ninyungu nini kubintu birebire, byoroshye.
Ndibuka umushinga wa shitingi-yuzuye neza. Pass ya mbere yari hamwe na 15-5PH. Nyuma yo gusaza, kugororoka kwari hanze. Twongeye kugorora hamwe na progaramu isobanutse, ariko ntabwo ari byiza. Twasabye C250 maraging ibyuma nkubundi buryo. Kurwanya ruswa ntibyari bikenewe (byari ahantu bifunze, bisize amavuta). Inzira ya maraging yaduhaye imbaraga, uburyo bworoshye bwo kuvura ubushyuhe hamwe no kugoreka gake, hamwe na machinable nziza muburyo bwo gukemura. Byari byiza. Nukugira ibikoresho palette hamwe nuburambe bwo kumenya igihe cyo gukandagira hanze yisanduku isanzwe idafite umwanda.
Ubu bwoko bwo guhuza ubumenyi ni ngombwa. Gukorana na nikel na cobalt alloys irakwigisha byinshi kubyerekeranye nimvura yimvura nubushyuhe bwo kuvura ubushyuhe. Ubwo bumenyi busubira muburyo dukemura amanota menshi ya PH. Byose birahujwe.
Imashini ya CNC: Imbyino ya Tooling na Coolant
Gukora PH idafite umwanda, cyane cyane mubihe byashaje, niho utwika ukoresheje ibikoresho bije niba utitonze. Birababaje kandi birakora cyane. Twakemuye amategeko make akomeye. Ubwa mbere, gushiraho gukomeye. Ibiganiro byose bizahita bikora-bikomere hejuru, bituma ubutaha bukurikira ikuzimu. Icya kabiri, ceramic cyangwa karbide yateye imbere yinjiza hamwe na geometrie ityaye. Ntabwo dukora ibyuma byihuta hano. Coolant ntishobora kuganirwaho, kandi igomba kuba amavuta menshi, ubwoko bwa sintetike, bwuzuyemo byinshi. Intego nugukuramo ubushyuhe hamwe na chip, ntukareke ngo yinjire mubice kandi birashoboka cyane kurenza imyaka.
Gucukura ibyobo byimbitse nikibazo cyihariye. Gucukura peck ni ngombwa, hamwe no gukuramo byuzuye kugirango bisukure kandi bikonjesha imyuzure kumyironge. Twangije imyanda mike ihenze hakiri kare tureka imitwe iratemba hanyuma dusudira mu myitozo, hanyuma ihita ifata umwobo. Noneho, gahunda zacu za CNC kuri ibyo bikoresho zifite ibiryo bigaburira / imbonerahamwe yihuta, yubatswe kuva imyaka yikigeragezo nikosa. Amakuru kurubuga rwabo, https://www.tsingtaocnc.com, ivuga kubushobozi, ariko ubushobozi nyabwo nububiko bwibitabo mububiko bwimashini hamwe nuburambe bwa programmes bacu bazi igihe cyo kubirenga.
Ubuso burangiza ibintu nabyo. Ubuso butunganijwe neza kuri PH buvanze burashobora kuba intumbero yo guhangayikishwa no gutangiza ruswa. Dukunze kwerekana urupapuro rwanyuma hamwe rwabigenewe rwo kurangiza cyangwa ndetse nigikorwa cyo gusya cyoroshye / gusya kumurongo hejuru yikimenyetso. Yongeraho ikiguzi, ariko kubice mubice byangirika, bihangayikishije cyane, ni ubwishingizi.
Kureba Inyuma no Kujya Imbere
Noneho, ibi bidusiga he imvura ikomera ibyuma bitagira umwanda? Numuryango wibikoresho bitangaje, ariko bisaba kubahana hamwe nuburyo bwa sisitemu. Ntabwo ari ibicuruzwa. Agaciro utanga azana ntabwo ari ugushonga no gusuka gusa cyangwa mugukoresha imashini ya CNC; ni muguhuza izo ntambwe na metallurgie.
Kuri QSY, imyaka mirongo itatu muri Igikonoshwa, gushora imari, no gutunganya bivuze ko twabonye ibi bibazo mbere. Twahinduye ibice, ibikoresho bimenetse, kandi twohereje ibizamini byo kugerageza kugirango dusaza umurongo neza. Ibyo kwibuka byinzego nibyo bibuza ibyo bibazo kugaruka kumushinga utaha. Iradufasha kuyobora abakiriya kure yimitego ishobora kubaho - nko kwerekana gusaza H900 kumyaka minini, yoroheje-ibice byogosha bizagoreka bidasubirwaho, cyangwa gutegura intambwe yo gusudira nyuma yo kuvura ubushyuhe bwa nyuma.
Ejo hazaza, ngira ngo, harimo no kurushaho kwishyira hamwe. Ahari gukoresha kwigana guhanura gusaza gushingiye kuri casting geometrie, cyangwa gukoresha cyane mugukurikirana mugikorwa mugihe cyo gutunganya kugirango umenye ibikoresho byambaye mbere yuko bigira ingaruka mubusugire bwubutaka. Ariko intandaro izagumaho: gusobanukirwa ko PH idafite inzira, ntabwo ari ibintu gusa. Ntabwo ugura akabari k'icyuma; urimo kugura ibyagezweho neza byubushyuhe bwumuriro nubukanishi. Kandi kubona urwo rutonde neza nibyo bitandukanya igice cyimikorere nigice cyizewe.
